A rocket fuel made from a frozen blend of water and aluminum nanoparticles has been developed by researchers at Purdue University. The propellant produces less pollution than other forms of rocket fuel and could be produced in situ on the Moon, Mars, or other off-planet sites in the solar system. The aluminum ice - ALICE - could also be used to generate fuel for fuel cells aboard long-distant spacecraft or an extraterrestrial base. The Purdue team is working with NASA, the Air Force Office of Scientific Research and Pennsylvania State University and has already employed ALICE to launch a 3-metre rocket.
It "is" rocket science, Alice!
